Definitions

  • the controller is adapted to determine a DC link voltage error signal, the DC link voltage error signal being the difference between a function of an actual DC link voltage and a function of a predefined reference DC link voltage, determine a DC link error power based on the DC link voltage error signal, determine a feed forward power, and generate a duty ratio for operating the power dissipating unit based on the DC link error power and the feed forward power.
  • modules with bidirectional voltage capability in the control circuit enables combination of the control circuit with a LCC HVDC scheme in which the polarity of the DC voltage changes when the direction of the transmitted power is inverted.
  • At least one primary switching block may include a second module, the second module including at least one second energy storage device. At least one second module may include at least one primary switching element to selectively direct current through the or each second energy storage device or cause current to bypass the or each second energy storage device. As indicated above with respect to the first modules, the construction of the or each second module in this manner allows its primary switching element(s) to be powered by its energy storage device(s), instead of an external power source, thus resulting a more compact control circuit.
  • control unit may selectively switch the or each switching element in the or each second module of the second current transmission path portion to block or minimise current flowing through the second current transmission path portion and thereby cause current to be directed into the or each energy conversion element.
  • control unit may selectively remove each energy storage device from the first and second current transmission path portions to generate an AC voltage (alternating voltage) waveform across the or each energy conversion element to remove energy from the power transmission lines.
  • a first control circuit 20 according to a first embodiment of the invention is shown in Figure 2 .
  • the first current transmission path portion 30 extends between the first and third terminals 22,34, and includes a plurality of series-connected first modules 36.
  • Each first module 36 includes two pairs of primary switching elements connected in parallel with an energy storage device in the form of a first capacitor.
  • the pairs of primary switching elements and the first capacitor are connected in a full-bridge arrangement to define a 4-quadrant bipolar module that can provide zero, negative or positive voltage and can conduct current in two directions.
  • the first control circuit 20 further includes an auxiliary terminal 42 and an energy conversion block extending between the third and auxiliary terminals 34,42 such that the energy conversion block branches from the current transmission path.
  • the energy conversion block includes a dump resistor 44 connected in series between the third and auxiliary terminals 34,42. It is envisaged that, in other embodiments of the invention, the dump resistor 44 may be replaced by a plurality of dump resistors.
  • the auxiliary terminal 42 is connected to the second DC power transmission line 28.
  • each 4-quadrant bipolar module is bypassed when the pairs of primary switching elements in each 4-quadrant bipolar module are configured to form a short circuit in the 4-quadrant bipolar module. This causes current in the first current transmission path portion 30 to pass through the short circuit and bypass the first capacitor, and so the 4-quadrant bipolar module provides a zero voltage, i.e. the 4-quadrant bipolar module is configured in a bypassed mode and thereby removed from the first current transmission path portion 30.
  • the control unit 46 also controls the switching of the plurality of secondary switching elements 40.
  • the first and second DC power transmission lines 26,28 interconnect first and second power converters 48,50 that are themselves connected to respective phases of corresponding first and second AC networks (not shown). Power is transmitted from the first AC network to the second AC network via the corresponding power converters and the first and second DC power transmission lines 26,28.
  • the first AC network In the event that the second power converter 50 is unable to receive the transmitted power as a result of, for example, a fault in the second AC network, the first AC network must temporarily continue transmitting power into the DC transmission lines until the power transfer can be reduced to zero, which is typically 1-2 seconds for a wind generation plant. This may lead to accumulation of excess energy in the DC power transmission lines 26,28. Removal of the excess energy from the DC power transmission lines 26,28 is required in order to protect the DC power transmission lines 26,28 from an overvoltage and to ensure a low voltage fault ride-through, if necessary.
  • the first control circuit 20 draws a relatively high current (typically 1.0 per unit) from the DC power transmission lines 26,28 and exchanges real power with the DC power transmission lines 26,28.
  • the first control circuit 20 can be used as an energy removal device to remove excess energy from the DC power transmission lines 26,28.
  • first modules 36 in the first control circuit 20 permits generation of a wide range of voltage waveforms to actively modify the current flowing through the dump resistor 44 so as to correspond to the excess energy to be removed from the DC power transmission lines 26,28.
  • each first capacitor from the current transmission path has been found to allow a fast transfer of energy, i.e. excess power, from the DC power transmission lines 26,28 to the first control circuit 20 and thereby enables rapid regulation of the energy levels in the DC power transmission lines 26,28. This in turn permits the first control circuit 20 to respond quickly to a requirement to regulate energy levels in the DC power transmission lines 26,28 in the event of a fault in an associated electrical network.
  • the second current transmission path portion 32 conducts a zero or near-zero current in the standby configuration and the energy removal mode. This thereby allows the use of low current, high voltage semiconductor devices in the second current transmission path portion 32, thus providing reductions in terms of losses, cost and footprint.
  • a second control circuit 120 according to a second embodiment of the invention is shown in Figure 4 .
  • the second control circuit 120 shown in Figure 4 is similar in structure and operation to the first control circuit 20 shown in Figure 1 , and like features share the same reference numerals.
  • control unit 46 controls the selective removal of each second capacitor from the second current transmission path portion 32.
  • Each second capacitor is selectively removable from the second current transmission path portion 32 as follows.
  • each of the plurality of second modules 68 can be configured to have a lower rating than each of the plurality of first modules 36 so as to provide reductions in terms of losses, cost and footprint. This is because, as also set out above with respect to the first control circuit 20, the second current transmission path portion 32 conducts a zero or near-zero current in the standby configuration and the energy removal mode.
  • a third control circuit 220 according to a third embodiment of the invention is shown in Figure 5 .
  • the third control circuit 220 shown in Figure 5 is similar in structure and operation to the second control circuit 120 shown in Figure 4 , and like features share the same reference numerals.
  • control unit 46 controls the selective removal of each second capacitor from the second current transmission path portion 32.
  • Each second capacitor is selectively removable from the second current transmission path portion 32 in the same manner as the selective removal of each first module 36 from the first current transmission path portion 30 in the first control circuit 20.
  • the operation of the third control circuit 220 is similar to the operation of the second control circuit 120.
  • the use of the 4-quadrant bipolar modules in the second current transmission path portion 32 is beneficial in that it permits use of the third control circuit 220 in combination with a LCC HVDC scheme in which the polarity of the DC voltage changes when the direction of the transmitted power is inverted.
  • a fourth control circuit 320 according to a fourth embodiment of the invention is shown in Figure 6 .
  • the fourth control circuit 320 shown in Figure 6 is similar in structure and operation to the third control circuit 220 shown in Figure 5 , and like features share the same reference numerals.
  • the fourth control circuit 320 differs from the third control circuit 220 in that:
  • the first and second DC power transmission lines 26,28 interconnect first and second power converters 48,50 that are themselves connected to respective phases of corresponding first and second AC networks (not shown). Power is transmitted from the first AC network to the second AC network via the corresponding power converters and the first and second DC power transmission lines 26,28.
  • the fourth control circuit 320 adopts a standby configuration in which the capacitors of the first and second modules 70 are connected in the current transmission path. Meanwhile the first and second current transmission path portions 30,32 are configured to maintain a zero or near-zero voltage across the dump resistor 44 in order to block or minimise current flowing through the dump resistor 44 and thereby minimise dissipation of energy via the dump resistor 44 when the fourth control circuit 320 is in the standby configuration.
  • the purpose of configuring the first and second current transmission path portions 30,32 in this manner is to minimise power losses through energy dissipation via the dump resistor 44.
  • the total voltage across the first current transmission path portion 30 is approximately equal to V DC , which is the voltage across the DC power transmission lines 26,28. In the standby configuration there is zero or minimal current flowing through the current transmission path.
  • the first AC network must temporarily continue transmitting power into the DC transmission lines until the power transfer can be reduced to zero, which is typically 1-2 seconds for a wind generation plant. As indicated above, this may lead to accumulation of excess energy in the DC power transmission lines 26,28. Removal of the excess energy from the DC power transmission lines 26,28 is required in order to protect the DC power transmission lines 26,28 from an overvoltage and to ensure a low voltage fault ride-through, if necessary.
  • the control unit 46 selectively removes each of the first and second capacitors from the first and second current transmission path portions 30,32 to generate a voltage waveform across each of the first and second current transmission path portions 30,32, which adds or subtracts finite voltage steps to the voltage across the DC transmission lines, V DC .
  • the voltage waveforms across the first and second current transmission path portions 30,32 are shaped so as to generate an AC voltage waveform across the dump resistor 44.
  • a simulation model of the fourth control circuit 320 has been implemented using Matlab-Simulink to illustrate its operation.
  • a representation of the simulation model is shown in Figure 8 in which each of the first and second capacitors are modelled as a DC voltage source and the fourth control circuit 320 is connected in parallel with a DC voltage source 74.
  • a square voltage waveform demand is set for each of the first and second current transmission path portions 30,32.
  • the positive peak of each square voltage waveform demand for each of the first and second current transmission path portions 30,32 is set to Vdc, while the negative peak of each square voltage waveform demand for each of the first and second current transmission path portions 30,32 is a negative voltage value controlled by a proportional-integral regulator so as to restore any lost energy in the first and second capacitors with a view to achieving a zero net energy exchange over a single cycle, as shown in Figure 9a which illustrates, in graph form, the change in power P 1 across the plurality of first modules 36 and a zero net power exchange indicated by a nil average power P avg .
  • the negative value of the generated voltage waveform causes a constant DC current to flow through the current transmission path from the second DC power transmission line 28 to the first DC power transmission line 26 to compensate for any loss of energy from the first and second capacitors to the dump resistor 44.
  • the constant DC current offsets the AC current flowing through the current transmission path to the dump resistor 44 as shown in Figure 9b which illustrates, in graph form, the instantaneous current I 1 and a zero average current I 1avg in the first current transmission path portion 30 and the instantaneous current I 2 and a zero average current I 2avg in the second current transmission path portion 32.
  • Figure 9c shows, in graph form, the instantaneous power P R and average power P Ravg dissipated in the dump resistor 44.
  • a fifth control circuit 420 according to a fifth embodiment of the invention is shown in Figure 10 .
  • the fifth control circuit 420 shown In Figure 10 is similar in structure to the second control circuit 120 shown in Figure 4 , and like features share the same reference numerals.
  • the fifth control circuit 420 differs from the second control circuit 120 in that:
  • the sixth control circuit 420 adopts a standby configuration in which each second capacitor is connected in the current transmission path. Meanwhile each auxiliary switching element 100 is switched to an off-state to inhibit flow of current in the dump resistor 44 to minimise energy losses.
  • each auxiliary switching element 100 is switched to an on-state to permit flow of current in the dump resistor 44.
  • the control unit 46 selectively removes each second capacitor from the second current transmission path portion to modify the voltage at the third terminal 34 to allow soft-switching of each auxiliary switching element 100 when each auxiliary switching element 100 is switched to an on-state.
  • each auxiliary switching element 100 switches to an on-state to cause a DC current to flow from the DC power transmission lines 26,28 through the current transmission path and into the dump resistor 44. This permits energy dissipation via the dump resistor 44 so as to remove excess energy from the DC power transmission lines 26,28.
  • each auxiliary switching element 100 is switched back to an off-state to inhibit flow of current in the dump resistor 44 before the fifth control circuit 420 is reconfigured in its standby configuration.
  • the control unit 46 selectively removes each second capacitor from the second current transmission path portion to modify the voltage at the third terminal 34 to allow soft-switching of each auxiliary switching element 100 when each auxiliary switching element 100 is switched back to an off-state.
  • the fifth control circuit 420 also provides a simpler configuration that is capable of removing energy from the DC power transmission lines 28,28.
  • the second current transmission path portion 32 can be configured to have a lower rating than the plurality of series-connected auxiliary switching elements 100 so as to provide reductions in terms of losses, cost and footprint. This is because selective removal of each second capacitor from the current transmission path is not essential to control the removal of energy from the DC power transmission lines 26,28.
  • each auxiliary switching element may be replaced by an auxiliary module to control flow of current in the dump resistor, each auxiliary module including at least one auxiliary energy storage device.
  • each auxiliary module includes at least one auxiliary switching element to selectively direct current through the or each auxiliary energy storage device or cause current to bypass the or each auxiliary energy storage device.
  • Each auxiliary module may be configured to have bidirectional current capability.
  • each auxiliary module may be configured to have bidirectional current capability in the same manner as the first and second modules of the current transmission path as set out above in the earlier embodiments.
  • each auxiliary switching element may be replaced by an auxiliary module that is configured to have unidirectional current capability, i.e. the or each auxiliary module is configured to be capable of conducting current in only one direction.
  • each auxiliary module may include first and second sets of series-connected current flow control elements, each set of current flow control elements including an active switching element to selectively direct current through the or each auxiliary energy storage device and a passive current check element to limit current flow through the auxiliary module to a single direction, the first and second sets of series-connected current flow control elements and the or each auxiliary energy storage device being arranged in a full-bridge arrangement to define a 2-quadrant bipolar rationalised module that can provide zero, positive or negative voltage while conducting current in a single direction.
  • one or more of the switching elements may be a different switching device such as a gate turn-off thyristor, a field effect transistor, an injection-enhanced gate transistor, an integrated gate commutated thyristor or any other self-commutated semiconductor device.
  • the switching device is connected in parallel with an anti-parallel diode.
  • the capacitor in each module may be replaced by a different energy storage device such as a fuel cell, a battery or any other energy storage device capable of storing and releasing its electrical energy to provide a voltage.
